Callie Torres fidgeted; she was pretty sure that she thought too much. Of course, she was a doctor, so of course she thought. There were still a few relationships and friendships that she was definitely over thinking and overanalyzing. She needed to be more like Mark Sloan, who didn't overanalyze, he was just horny, and everyone knew that. If you were with Sloan, you knew what you were going to get, a good time. She wished that she was like that. That doesn't mean that she wanted to be known as the female Mark Sloan, she just didn't want to deal with thinking about relationships anymore. She was sleeping with Sloan at almost every chance they got, but it wasn't quite the relationship that she wanted, and he wasn't quite the person that he wanted, and damn it, that just wasn't fair. Emotions got in the way of her having sex, and she wasn't sure if she liked that.

Her stomach growled, which reminded her of other feelings, the feeling of hunger. She glanced up from some paperwork to see Hahn walking toward the cafeteria. Amazing timing they had. "Erica!" The other woman looked up and smiled expectantly at Callie, and it made Callie wish that the only feeling she felt right then was hunger. "Do you wanna get lunch?"

Erica nodded but was a bit confused at Callie's question, "Don't we usually?"

"Well, yes, but…Yes." Callie could have smacked herself for that one. Of course they usually had lunch together; she didn't really need to ask the question. She just had spent so much time overanalyzing that she wanted to make sure that Erica really wanted to get lunch with her…or something. Too much thinking.

Sloan passed the two women and noticed Callie's obvious nervousness, "Are you all right, Torres?" She shrugged, so he did what he did best, he turned her nervousness into something sexual, "Still thinking about a threesome?"

Callie visibly paled and ignored him, then grabbed Erica's arm to lead her into the cafeteria while muttering, "Food. Now."

Erica had noticed that Callie was more quiet than usual, but this was the weirdest lunch to date. After five minutes of Callie staring at her salad, Erica decided to interrupt her thoughts. "I don't usually agree with Mark Sloan, but…" Callie's head immediately popped up at the mention of Sloan, irrationally afraid that he would somehow hear his name and mention a threesome again. "Are you okay?"

"Yes," Callie nodded confidently then took a bit of her food. "No," she admitted after chewing a bit. Erica raised her eyebrows at this, and was still trying to think of the right thing to say when Callie started to talk about her salad and how good it was.

Erica realized that Callie was doing her best to change the subject, but she was failing horribly, so, Erica sighed and took one for the team. "Look at them fight over the Sparkle Pager." Hahn laughed and looked at Torres expectantly but received no answer. "I said, look at them fight over that Sparkle Pager!"

"What?"

"I said that I was glad that we didn't have to deal with that Sparkle Pager."

"Oh," Callie looked over to see Christina and Izzie fighting over the pager, apparently one of them had stolen it off of Meredith for the moment. "Yeah, I'm glad we don't have to do that."

Hahn sighed and put her fork down. "Geez, Callie. What has gotten into you lately? You're acting like them, weird and distant." Hahn gestured over at the interns and first years that were all in their little cliques, arguing or discussing 'important' matters.

"Sloan."

"Sloan has gotten into you?" It took a moment for that to sink in with Erica, then her eyes widened immediately. "Oh…." She took a deep breath, "Okay, that I did not need to hear. We're friends, but I did not need to hear that about Mark Sloan."

Understanding what Erica thought she had meant, Callie smirked, "Not like that."

"Oh?"

"He's just…putting ideas into my head."

Erica leaned forward with her elbows on the table, trying to lean closer to hear what she assumed was some good gossip. "Ideas?"

Callie nodded before whispering, "Like Addison."

"He's making you think about Addison?"

"No! He's thinking like Addison." Callie stressed the word 'Addison' to try to get Erica to remember that Addison had thought that they were lovers.

Erica just rolled her eyes at the theory. "It's Sloan, of course he's thinking about sex." Hahn paused for a moment before continuing her train of thought, "The thought of you and me…does it really bother you that much? It's just Addison and Sloan. We both know that their judgment isn't the best."

Callie paused for a moment, considering the idea. Realistically, she wasn't into women; she liked men. However, the way that Erica looked at her; she really just wanted to lean across the table and… "I should go!" Torres stood up quickly, forgetting about her half-eaten salad.

A very confused Hahn was left sitting at the table, as she watched Callie snake her way over to Mark, who sighed impatiently. "I've been signaling to you for five minutes!"

"Sorry."

"It's okay. You were busy with Hahn…" He paused as his words sank into his own mind. He wiggled his eyebrows suggestively, "We could be busy with Hahn in another sense."

Callie rolled her eyes and tugged on the waistline of his pants. "On-call room…Now!"

Callie wasn't much for foreplay at that moment. She just wanted Sloan. She wanted everything. There were a few brief kisses, as he allowed his kisses to travel down her neck, and she allowed her eyes to flutter shut. He began working on lowering her pants, with her eager to help him as…

Erica was finally done for the day. In fact, she was just slipping into her car, ready to go for a drink or to even just go home and take a long bath when Callie interrupted her thoughts. "Erica, I need to talk to you."

"Are you finally going to tell me what's wrong?" Callie nodded, so Erica motioned for her to get into the passenger side of the car.

"This."

Erica looked surprised, "This?" She looked around at the interior of her car.

"Us."

"More than one word responses would be helpful here, Callie."

"I don't want a threesome." Erica didn't look any less confused. "Sloan does."

"I know…"

"I know that you know." Ugh, that was not how it was supposed to be at all. She was not supposed to sound like a little kid saying things like 'I know that you know that I know that he knows that…' Callie was going to make it simple. Well, really it was the look that Erica was giving her that made it all a bit simpler. Erica was so amazingly beautiful and talented…And then Callie was kissing her, and to Callie's surprised and delight, Erica was kissing her back.

Torres was so excited to be done having to try to explain herself, because now she could explain by lacing her left hand up into Erica's hair, and Erica was busy doing that thing she did with her thumb, where she swiped it over Callie's cheek. It drove Callie crazy, and suddenly Callie was glad that it was dark out, so no one could see as she pushed the armrest up, so that she could slide closer to Erica.

Erica didn't seem to mind at all as she helped Callie take her jacket off, and Callie wasn't entirely sure how this kind of thing worked with women, but her instincts seemed to be telling her to work on Erica's shirt, and she seemed okay with that, because she moaned a little bit and leaned in Callie's touch. They twisted and turned to try to get as close as they could, which was a bit of a struggle in a car, but they were making it work, and the windows were starting to fog, which Callie thought only happened In movies, not in hospital parking lots, but Erica's thumb was back up on her cheek during its swiping thing that drove her crazy. It wasn't Callie's fault when Erica's nice buttoned shirt lost a few buttons, nor was it her fault when she murmured happily when Erica's hand found its way onto her thigh. Erica was looking at her with questioning eyes and Callie was guiding her hand when she leaned back against the steering wheel and the horn and…

"That's me." Callie opened to eyes to see Mark leaning over her and checking his buzzing pager. "You okay?"

"Yes, yeah. It's been a long day." Callie scrunched her eyes together tightly for a moment. She had just daydreamed about another woman while having sex, not only that, but it had a storyline. Mark looked worried, even as he reached over and snatched up his pager. Callie patted his arm reassuringly. "You're a good boy. Don't worry. It's not you."

"You sure?" Callie nodded and gave him a quick kiss. "Maybe later then?"

Callie smiled weakly at this, but she hoped it reassured him. It seemed to, because a moment later he was back up and readjusting his clothes. "I have to go…" She nodded, and he smiled at her before leaving.

Callie readjusted her clothing as well and sat back down. Torres didn't know everything, but she was pretty sure that friends don't think about friends during sex with a perfectly good looking man. She realized she thought about Erica Hahn entirely too much, but if Sloan could keep his mouth shut about threesomes with her, then maybe, it'd be okay…at least for another day.
